Hi Raphael, Support team help me to do this in code but it's also nice to know we can do things different ways.
Thank you once again

Hello, I would also need help on this similar topic. I am trying to search the data for a specific string, and put that entire line in a String Variable.

How do I go about getting the entire line after using the find() function?

example:

PP is declared as a string

if(find('PURCHASE PRICE',2,2,37,80))
&PP := %Store entire line where PURCHASE PRICE is found
endif()

Find only returns a yes or no, it doesn't tell you where it found the search string.
To do that you need to check each line one by one.
for(&current.line,1,1,37)
if(pos('PURCHASE PRICE',@(&current.line,1,80))>0)
exit
endif
endfor()
&PP := @(&current.line,1,80)
